ROLL-HOUSING.

' Patented Mar .4,1913.

To all whom it may concern Be it known that I, WILLIAM Jo nson, a citizen of the United States, residing .at

State of Indiana, have invented certain new .and useful Improvements in Roll-Housings,

of which the following is a specification, reference being had therein to the accompanying drawing.

Th's invention relates to roll housings and has specialreference to that type of rollf wherein the bottomroll constitutes the movable roll and the top roll remains stationary,

the bottom I'OllbQlDg drawn upward, thus preventing the driving roll from gettingout of alin'ement.

Another'object of the invention is to pro-- vide a convenient means of improved char acter whereby the rolls may be readily assembled or disassembled so that the rolls themselves can be quickly changed.

With-the above-and other ob ects in view, the invention consists in general of certain novel features of construction, combinations and arran ements of parts as willbe hereinafter accompanying drawings, and specifically claimed. I. in the accompanying drawings, like characters of reference indicate like' parts in the several views, and Figure 1 is an end elevation of a roll housing constructed in accordance with this invention. Fig. .2 is a side elevation thereof. Fig. 3 is a section on the line 33,Fig. 2. Fig. 4 is a detail section with the parts in their disassembled position. Fig. 5 is a face view of one of the bearings. Fig. 6 is a section on the line 6-6, Fig. 5. Fig. 7 is a detail perspective view of the ca horizonta plane through one of the bearings showing the manner of adjusting the same laterally.

A roll housing constructed in accordance with this invention comprises a base portion 10 wherefrom extend flanges 11 bymeans of which the housing is bolted to-a suitable foundation. Legs 12 extend upward from the base and are provided with reinforcing ribs 13. These legs have inwardly extendly described, illustrated in the- Fig. 8 is a section taken in a ing portions 14 the inner faces of which are sary he're to be shown, can be secured, Ex-

tending vertically through each leg isan opening 19, and it will be noted that these openings extend through the overhanging 0 portions of the legs so that bolts 20 can pass through the openings and enter the portion 16 of the guide-slot.

Secured upon the lower ends of the bolts 20 by means'of tapering pins 21 is a'bottom block 22 which is recessed as at 23 for the-I reception of alower-roll bottom guide block 24. This guide block is recessed on the upper side as at 25 for the reception of a journal bearing 26 of bronze or other suitable metal. In the journal bearing 26 is held the journal 27 of the bottom roll 28. On top of this journal 27 .is a ca 29 which serves to hold the journal in p ace in its bearing. On top of this member 29 isa rubber pad 30 whereon rests the upper roll bottom bearing 31 upon which revolves a journal 32.

At 33 is shown the upper roll cap which is recessed for the reception of the journal bearing 34 preferably of bronze or other like material.

The members 12 have the overhung portions 14 extending upwardly as at 35 so as to form a shoulder on the outside of each of these portions. On the upper end of these members 12 is fitted"a frame cap 36 provided with suitable openings for the reception of bolts 20. This cap fits closely on the upper ends of the members 12 and is held 1n; place by bolts 37 having enlar ed heads 38, the said bolts sliding latera ly into slots 39 having enlarged bottoms 40 which are formed in the respective members 12. These bolts 37 pass through suitable o enings in the frame cap 36 and are held t erein by means of nuts 41 so that when the bolts are slid into position the nuts 41 may be tightened very slightly and yet hold the frame cap on the frame. When enlarged is necessary to remove the frame cap a half turn maybe given to thenuts and the bolts slid out of position when the cap may be removed. Upon the bolts 20 'are nuts 42 by means of which the distance between the roll 28 which has the journal 27 and the roll 43 having the journal 32 may be varied. It will, of course, be ob- I entirely removed from the bolts and the nuts 41 loosed as previouslydescribed. It. "willbe obvious that by raising'the lower roll in this manner there will be no tendency to crowd the same to one side or the other as is frequently the case when a compressIon screw is usedon the upper roll. 1 The rolls will thus maintain proper position with relation to each other and this will be "greatly aided by the interposition of the rubber block 30. p i or At 44 are shown certain bolts which are used for eliminating the end movement or lash of' the-rolls. These bolts 44 haveftheir ends bearing,againstflanges 45 sformed on the bearings as can be seenbyfreference to, Fig. S-sothatthesebearings, can be moved e housings to hold the rolls and eflicient device of the kind described transversely ofth in proper position. l p I i 4 There has thu been provided a simple and fort-he purpose specified.

It is obvious that many minor changes may be madein the form-and construction principles thereof and it is therefore not wished to confine the invention to the exact form herein shown and described, but it is wished to include all such as properly' "thereof without departing from the material come within the scope of the appended claimm is claimed as new,

i A roll housing coihprising a frame havll'lg SldG arms positioned 1n spaced relatlon" to providea slot between the arms, the lower portions'of the arms being -reduced to provide an enlarged'pocketat the lower end of theslot, a supporting block slidably mounted'in said pocket, adjusted rods ex-' tending from said supporting block and passing vertically through said arms, a guiding block carried by said supporting; block and passing betweensaid arms, a bearing carried by said guiding block, a second bear-- ingpositioned above said first mentioned bearing, a resilient pad resting upon said. second-bea ring,-a third bearing resting upon:

said resilient pad, acap) mounted in the upper portion ofthe' slot etween said arms,

a bearing' carried ,by said cap, and means for vertically adjusting said supporting block to 'hold-'said bearings in operative relation. I I v In testimony whereof I hereunto .aflixmy signature inpre'sence of two witnesses.
